A series of attacks on a convoy of aid vehicles in Somalia in recent days is now thought to have left around twenty people dead.

Some were killed when the convoy was ambushed by militia, others when one of the vehicles hit a landmine.

The victims included security personnel accompanying the convoy and civilians caught in crossfire.

The convoy, which is under heavily-armed protection, has been trying to deliver food aid donated by the US-based agency, Care International.

The food is intended for the southern region of Bakol which has been affected by famine.
